Abstract
Biodiversity is the variety of different forms of life on earth, including the different plants, animals, micro-organisms, the
genes they contain and the ecosystem they form. It refers to genetic variation, ecosystem variation, species variation
(number of species) within an area, biome or planet. Relative to the range of habitats, biotic communities and ecological
processes in the biosphere, biodiversity is vital in a number of ways including promoting the aesthetic value of the natural
environment, contribution to our material well-being through utilitarian values by providing food, fodder, fuel, timber
and medicine. Biodiversity is the life support system. Organisms depend on it for the air to breathe, the food to eat, and
the water to drink. Wetlands filter pollutants from water, trees and plants reduce global warming by absorbing carbon,
and bacteria and fungi break down organic material and fertilize the soil. It has been empirically shown that native
species richness is linked to the health of ecosystems, as is the quality of life for humans. The ecosystem services of
biodiversity is maintained through formation and protection of soil, conservation and purification of water, maintaining
hydrological cycles, regulation of biochemical cycles, absorption and breakdown of pollutants and waste materials
through decomposition, determination and regulation of the natural world climate. Despite the benefits from biodiversity,
today’s threats to species and ecosystems are increasing day by day with alarming rate and virtually all of them are
caused by human mismanagement of biological resources often stimulated by imprudent economic policies, pollution and
faulty institutions in-addition to climate change. To ensure intra and intergenerational equity, it is important to conserve
biodiversity. Some of the existing measures of biodiversity conservation include; reforestation, zoological gardens,
botanical gardens, national parks, biosphere reserves, germplasm banks and adoption of breeding techniques, tissue
culture techniques, social forestry to minimize stress on the exploitation of forest resources.
Key words: Biodiversity, conservation, ecosystem services
Introduction
Biodiversity is a comprehensive umbrella term for
the extent of natures variety or variation within the
natural system; both in number and frequency. It is
often understood in terms of the wide variety of
plants, animals and microorganisms, the genes they
contain and the ecosystem they form. The
biodiversity we see today is the result of billions of
years of evolution, shaped by natural processes and,
increasingly, by the influence of humans. It forms
the web of life of which we are an integral part and
upon which we so fully depend. So far, about 2.1
million species have been identified, mostly small
creatures such as insects. Scientists believe that
there are actually about 13 million species, though
as per UNEP estimates there are 9.0 to 52 million
species exist on earth (Mora et al., 2011). Biodiversity

also includes genetic differences within each species for example, between varieties of crops and breeds of
livestock. Chromosomes, genes, and DNA-the building
blocks of life-determine the uniqueness of each
individual and each species. Yet another feature of
biodiversity is the variety of ecosystems such as those
that occur in deserts, forests, wetlands, mountains,
lakes, rivers, and agricultural landscapes. In each
ecosystem, living creatures including human form a
community, interacting with one another and with the
air, water, and soil around them. Biodiversity is thus
considered at 3 major levels:
Genetic diversity: This is the variety of genetic
information contained in all of the individual plants,
animals and microorganisms occurring within
populations of species. Simply it is the variation of
genes within species and populations.

BENEFITS OF BIODIVERSITY
Utilitarian benefits
Biodiversity contribute to our material well-being. We
obtained various productive materials from biodiversity
e.g. agricultural materials or food, medicine, industrial
raw materials etc.
 More than 60 wild species have been used to
improve the world’s 13 major crops by providing
genes for pest resistance, improved yield, and
enhanced nutrition (IUCN, 2012).
 Since agriculture began about 12,000 years ago,
roughly 7,000 plant species have been used for
human consumption. While most people depend
mainly on domesticated species for their dietary
needs, some 200 million depend on wild species for
at least part of their food.
Ecosystem services
Ecosystem services are defined as the processes and
conditions of natural systems that support human
activity (Singh et al. 2006).
 Biodiversity plays an important role in the
way ecosystem function and in the services they
provide. Biodiversity plays a major role in
mitigating climate change by contributing to longterm sequestration of carbon in a number of biomes.
It is through biodiversity that sequential balance of
CO2 and O2 is maintained. Due to the accumulation
of CO2 in the atmosphere and ozone layer depletion,

to five times more carbon than the equivalent area
of mature tropical forests. But these areas are being
destroyed three to four times faster than forests,
releasing substantial amounts of carbon dioxide into
the atmosphere and the ocean, and contributing to

Biodiversity underpins ecosystem resilience and
plays a critical role as part of disaster risk reduction
and peace-building strategies. Forests, wetlands and
mangroves play a critical role in reducing the
impacts of extreme events such as droughts, floods
and tsunamis. The value of the ecosystem services
provided by coral reefs ranges from more than US$
18 million per square kilometer per year for natural
hazard management, up to US$ 100 million for
tourism, more than US$ 5 million for genetic
material and bio-prospecting and up to US$
331,800 for fisheries (CBD, 2014).
Protective services of biodiversity provide
protection of human beings from harmful weather
conditions by acting as wind breaks, flood barriers
among others.
Production of at least one third of the world’s food,
including 87 of the 113 leading food crops, depends
directly or indirectly on pollination carried out by
insects (honey bee), bats and birds. This worldwide
economic value of the pollinating service provided
by insects is worth over US$ 190 billion per year
for the main crops that feed the world (CBD, 2014).
There have been worldwide declines in
the diversity of pollinating insects that are essential
for the reproduction of many plants.
 Wild species are important in pest regulation. Bats,
toads, birds, snakes, and so on consume vast
numbers of the major animal pests found on crops
or in forests.
 A single colony of Mexican Free-tailed Bat eats
more than 9,000 kg of insects per night, targeting
especially Corn Earthworms and Fall Armyworms,
both major crop predators. Yet 18% of bat species
are threatened with extinction.
 A single brood of woodpeckers can eat 8,00012,000 harmful insect pupae per day, helping to
maintain the health of forests, whilst in fruit
plantations, insectivorous birds can make the
difference between a bumper crop or a costly
failure.
Ethical and moral benefits
Every form of life on earth is unique and warrants
respect regardless of its worth to human beings; this is
the ecosystems right of an organism. Every organism
has an inherent right to exist regardless of whether it is
valuable to human beings or not. Humankind is part of
nature and the natural world has a value for human
heritage. The well being of all future generations is a
social responsibility of the present generations, hence
the existence of an organism warrants conservation of
the organism.
Aesthetic value
Human beings derive great enjoyment from natural
environment. The shapes, structure and colour
stimulate our senses and enrich our culture. This
illustrate majorly in the popularity of biodiversity
conservation measures and the myriad of the many
organizations which fight for the protection of different
organisms. A lot of money is paid to conserve wildlife
for their value in nature through so many organizations.
Wild species enhance our appreciation and enjoyment
of the environment through:
 Leisure activities e.g. bird watching and nature
trailing;
 Spotting activities e.g. spot hunting, sport
fishing, diving and mushroom picking;
 Hearing, touching or just seeing wildlife;
 Enjoyment as seen in art and culture e.g. dolls
and teddy bears.

LOSS OF BIODIVERSITY
The loss of biodiversity and the related changes in the
environment are now faster than ever before in human
history and there is no sign of this process slowing
down. Virtually all of Earth’s ecosystems have been
dramatically distorted and altered by human activities
and continuously be converted for agricultural and
other uses. Many animal and plant populations have
declined in numbers and geographical spread.
However, species extinction is a natural part of Earth’s
history but human activity has increased the extinction
rate by at least 100 times compared to the natural rate.
Loss of biodiversity is caused by a range of drivers. A
driver is any natural or human-induced factor that
directly or indirectly causes a change in
an ecosystem. A
direct
driver unequivocally
influences ecosystem processes. An indirect driver
operates more diffusely by altering one or more direct
drivers. Important direct drivers affecting biodiversity
are habitat alteration, climate change, invasive species
overexploitation and pollution.
Principal threats to biodiversity
A threat by definition refers to any process or event
whether natural or human induced that is likely to
cause adverse effects upon the status or sustainable use
of any component of biological diversity. Biodiversity
is declining rapidly due to factors such as habitat
alteration and destruction by the land use change, over
exploitation of biological resources, climate change,
pollution and invasive species. Such natural or humaninduced factors tend to interact and amplify each other.
Habitat alteration and destruction
Overall, the main factor directly driving biodiversity
loss worldwide is habitat alteration and destruction.
Habitat destruction renders entire habitats functionally
unable to support the species present in the habitat.
Biodiversity reduced in this process when existing
organisms in the habitat are displaced or destroyed
(Ayoade at al., 2009; Agarwal et al., 2011). Human
destruction of habitats has accelerated greatly in the
latter half of the twentieth century. Natural habitats are
often destroyed through human activity for the purpose
of harvesting natural resources for industry production
and urbanization. Clearing forest areas for agriculture,
changes in the riverine habitat to lacustrine (reservoir)
habitat by the construction of hydroelectric projects on
the rivers (Agarwal et al., 2014), mining, logging,
urban sprawl, construction of highways are some
examples of habitat destruction and fragmentation. A
five-year estimate of global forest cover loss for the
years 2000–2005 was 3.1 percent. In the humid tropics
where forest loss is primarily from timber extraction,
272,000 km2 was lost out of a global total of
11,564,000 km2 (or 2.4 percent). In the tropics, these
losses also represent the extinction of species because
of high levels of endemism. Increased greedy demand
for resources has resulted into land use changes. Hence
loss to genetic diversity, species reduction and
increased ecosystem changes such as random
population changes, disease outcrop, and habitat
fragmentation among others has resulted into
biodiversity losses.
Over-exploitation of biological resources
This results when individuals of a particular species are
taken at a higher rate than can be sustained by the
natural reproductive capacity of the population being
harvested. This can be through hunting, fishing, trade,
food gathering etc. Overexploitation remains a serious
threat to many species, such as marine fish and
invertebrates, trees, and animals hunted for meat. The
grazing pressure on most of the high altitude grasslands
of the Uttarakhand state both from migrant and local
communities, is the extensive extraction of medicinal
herbs in these areas resulting in their over exploitation
(Rawat, 1998). Most industrial fisheries are either fully
or overexploited, while destructive fishing techniques
harm estuaries and wetlands. Although the true extent
of exploitation is poorly known, it is clear that rates of
off take are extremely high in tropical forests. The trade
in wild plants and animals and their derivatives is
poorly documented but is estimated at nearly $160
billion annually. It ranges from live animals for the
food and pet trade to ornamental plants and timber.
Because the trade in wild animals and plants crosses
national borders, the effort to regulate it requires
international
cooperation
to
safeguard
certain species from overexploitation.
Pollution
Over the past five decades, inorganic and organic
pollutants have emerged as one of the most important
factor of biodiversity loss in terrestrial, aquatic- marine
as well as freshwater ecosystems. Thermal pollution is
another threat to biodiversity. The potential
consequences of organic pollutants in a freshwater
ecosystem include eutrophication of fresh-water body,
hypoxia in coastal marine ecosystems, nitrous oxide
emissions contributing to global climate change, and air
pollution by NO in urban areas. Occurrence of such
problems varies widely in different regions. Species in
habitats are increasingly being harmed by industrial

activities and pollution from excessive use of agrochemicals such as DDT, oil spills, acid precipitation
etc. For example pesticide linked decline of fish eating
birds and falcons. Lead poisoning is another major
cause of mortality of many species such as ducks,
swans and cranes as they ingest the spent shotgun pellet
that fall into lakes and marshes.
The vulture was once very common in the Gangetic
plains of India, and often seen nesting on the avenue
trees within large cities in the region. Before the 1990s
they were even seen as a nuisance, particularly to
aircraft as they were often involved in bird
strikes. The vulture has suffered a 99% population
decrease in India (Prakash, 2007) and become rare due
to poisoning by DDT used as pesticides and also by
diclofenac which is used as veterinary non –steroidal
anti- inflammatory drug, leaving traces in cattle
carcasses which when fed by vultures leads to thinning
of egg shells resulting into premature hatching and
kidney failure in birds (Green et al., 2004;
Muralidharan et al., 2008). Campaigns to ban the use of
diclofenac in veterinary practice have been underway
in several South Asian countries.
The dramatic decreases in house sparrow population in
India is experienced in recent past. It is linked with
pollution caused by electromagnetic radiation from
mobile phones. Microwave towers (Balmori and
Hallberg, 2007); the excessive use of pesticides, a
gradual decrease in nesting sites caused by changes in
urban building design. To promote the conservation of
these birds, in 2012, the then Chief Minister of Delhi,
Ms. Sheila Dikshit, declared the house sparrow as the
state bird of Delhi.
Species invasions
This can be intentional or accidental. Species
introduced in an ecosystem will cause changes in the
ecosystem. Introduced species are organisms arising in
areas/ habitats in which they were previously not
native. Such introduced species are usually referred to
as biological pollutants. Some of the ecological impacts
of the invasion include hybridization, out competition,
disruption of original ecosystem, plant pathogenic
influences, disease transmission, disruption of foodwebs, and to some situations extinction. Species may
be introduced intentionally for ornamental concerns,
agriculture, hunting and spotting activities,
biotechnology for scientific research and for trade.
Climatic changes
This is of great concern especially when global CO2
increases in the atmosphere resulting to global
warming. Most species originate within a very narrow
physiological limit; hence nature has a range of
tolerance maintained for ecosystem stability. Changes
may be gradual or abrupt such that if the limit is
exceeded the upper or lower, species suffers extinction.
Recent changes in climate, such as warmer
temperatures in certain regions, have already had
significant impacts on biodiversity and ecosystem
(Rawat and Semwal, 2014). They have
affected species distributions, population sizes, and the
timing of reproduction or migration events, as well as
the frequency of pest and disease outbreaks. Projected
changes in climate by 2050 could lead to the extinction
of many species living in certain limited geographical
regions. By the end of the century, climate change and
its impacts may become the main direct driver of
overall biodiversity loss. While the growing season in
Europe has lengthened over the last 30 years, in some
regions of Africa the combination of regional climate
changes and human pressures have led to decreased
cereal crop production since 1970. Changes in
fish population have also been linked to large-scale
climate variations such as "El Nino" have affected
fisheries off the coasts of South America and Africa,
and decadal oscillations in the Pacific have affected
fisheries off the west coast of North America.
As climate change will become more severe, the
harmful impacts on ecosystem services will outweigh
the benefits in most regions of the world. The
Intergovernmental Panel on Climate Change (IPCC)
project that the average surface temperature will raise
by 2 to 6.40C by 2100 compared to pre-industrial
levels. This is expected to cause global negative
impacts on biodiversity (Millennium Ecosystem
Assessment, 2005).
Population
From 1950 to 2011, world population increased from
2.5 billion to 7 billion and is forecast to reach a plateau
of more than 9 billion during the 21st century
(Population Reference Bureau). As the human
population is increasing, there exists insatiable demand
for raw materials which is bound to cause changes in
biodiversity. The human population has more impact
on biodiversity than any other single factor. According
to Dumont, (2012) until the middle of the 21st century,
worldwide losses of pristine biodiversity will largely
depend on the worldwide human birth rate. It is
therefore vital to control human population which will
result in biodiversity conservation.

Institutional / policy failure
Some institutions are created to manage biological
resources. However, the institutions/policy fail to
internalize the values of biodiversity within the
decision making process of their Nations and
individuals. Such institutions/policies in place should
have a holistic approach towards biodiversity
conservation rather than part conservation.
BIODIVERSITY CONSERVATION
Biodiversity conservation is about saving life on Earth
in all its forms and keeping natural ecosystems
functioning and healthy. This incorporates the
preservation, maintenance, sustainable use, recovery
and enhancement of the components of biological
diversity. Where - Conservation - is the sustainable use
of resources and encompasses protection as well as
exploitation and, Preservation - is an aspect of
conservation meaning to keep something without
altering or changing it. Sustainable development is
another intricate aspect of biodiversity conservation.
This refers to development that meets the needs of the
current generation without compromising the ability of
future generations to meet their needs. It simply refers
to intra and intergenerational equity. A balance
between the environment, development and society
results to sustainable development which ensures
biodiversity conservation. This is only possible in the
presence of proper enforcement and implementation
policies/ conventions and environmental institutions.
Why Conserve Biodiversity?
Biodiversity is the life support system of our planet- we
depend on it for the air we breathe, the food we eat, and
the water we drink. Medicines originating from wild
species, including penicillin, aspirin, taxol, and quinine,
have saved millions of lives and alleviated tremendous
sufferings. Wetlands filter pollutants from water, trees
and plants reduce global warming by absorbing carbon.
Bacteria and fungi break down organic material and
fertilize the soil. It has been observed that native
species richness is linked to the health of ecosystems,
as is the quality of life for humans. The connections
between biodiversity and our sustainable future appear
closer and closer the more we look. We literally need to
conserve biodiversity as our lives depend on it.
Conservation measures of biodiversity
Ex-situ conservation:
It refers to conservation of components of biodiversity
outside their natural habitats, e.g. zoos, museums, gene
banks, botanical gardens/arboretums, used for
threatened and endangered species to avoid their
extinction, also known as captive conservation.
A lot of effort is under way to collect and preserve the
genetic material of crops, animal, bird and fish species
(Agarwal et al., 2009; Agarwal, 2011). This work is
being done by institutions such as the National Bureau
of Plant Genetic Resources, National Bureau of Fish
Genetic Resources, the National Bureau of Animal
Genetic Resources, etc. Conservation measures have
also
included reintroduction,
captive-breeding
programs and artificial feeding. Reintroduction of an
animal or plant into the habitat from where it has
become extinct is another form of ex situ conservation.
For example, the Gangetic gharial has been
reintroduced in the rivers of Uttar Pradesh, Madhya
Pradesh and Rajasthan where it had become extinct.
Seed banks, botanical, horticultural and recreational
gardens are important centers for ex situ conservation.
Ex-situ conservation measures complement to in-situ
conservation.
In-situ conservation:
It refers to conservation of ecosystems and natural
habitats including maintenance and recovery of viable
populations of species in their natural habitats.
Approximately, 4.2 % of the total geographical area in
India has been earmarked for extensive in-situ
conservation of habitats and ecosystems. A protected
area network of 102 national parks, 18 biosphere
reserves and 448 wildlife sanctuaries has been created.
The results of this network have been significant in
restoring viable population of large mammals such as
tiger, lion, rhinoceros, crocodiles and elephants.
Community
Participation
in
Biodiversity
Conservation
It is being recognized that no legal provisions can be
effective unless local communities are involved in
planning, management and monitoring conservation
programmes. There are several initiatives to do this,
both by government as well as non-governmental
organizations. For example, the Joint Forest
Management philosophy stresses involvement of
village communities in regenerating and protecting
degraded forest land in the vicinity of villages.
Successful conservation strategies will have to have the
confidence and participation of the local communities
(Dobhal et al., 2011).
International efforts for biodiversity conservation:
Conserving biodiversity is not an issue confined to any
one country or community. It is a crucial global
concern. Conservation of biological diversity and

sustainable use of its components came into the
limelight in 1972 (United Nations Conference on
Human Environment; Stockholm). In 1973, UNEP
identified conservation of biodiversity as a priority
area, hence there was need to get the legal mandate for
conservation of world resources. There were
negotiations for a legally binding instrument to address
biological diversity and its loss to enhance fairness and
equity in sharing of the benefits of biodiversity; this led
to the opening of the Convention on Biological
Diversity in 1992; (CBD, 2011).The convention was
inspired by the growing concern all over the world for
sustainable development. The convention objectives
were:
 Conservation of the biological diversity
 Sustainable use of its components;
 A fair and equitable sharing of its benefits.
This was the first global comprehensive agreement that
addressed all the aspects of biological diversity; genetic
resources, species diversity and ecosystem diversity.
Several international treaties and agreements are in
place in the attempt to strengthen international
participation and commitment towards conserving
biodiversity. Some of these are:
 Rio–de-Janeiro under the United Nations
Conference on Environment and Development
(UNCED)/ Earth Summit
 African Convention on Conservation of nature and
natural resources.
 The Ramsar Convention on Wetlands of
international importance.
 International Union for the Conservation of nature
(World Conservation Union).
 Convention on International trade for endangered
species (CITES).
 International Convention for the Protection on
birds.
 International Board for Plant genetic resources.
 World Resources Institute.
 World Wide Fund for Nature.
 Convention on Conservation of migratory species
of wild animals.
 International Convention for the Regulation of
whaling.
 UNESCO programme on Man and biosphere.
Indian efforts for biodiversity conservation
In India, protecting and promoting biodiversity has
always been an integral part of culture and civilization.
This can be seen in the thousands of sacred groves that
are found all over the country. The Indian traditional
systems of agriculture and medicine depend on plant
and animal biodiversity. India is one of the early
signatories to the UN Convention on Biological
Diversity (CBD). Even prior to CBD, India has already
been having legal provisions dealing with aspects
relating to biodiversity.
Indian Forest Act 1927 and Forest (Conservation) Act
1980 deal with management of forests and
conservation of forest land respectively. Wildlife
(Protection) Act 1972 is for the protection of wild
animals, birds and plants, and basically aims at
protecting, propagating or developing wildlife or its
environment through national parks, sanctuaries etc.
Besides, the Act has a provision to prohibit picking and
uprooting of specified plants.
Despite population pressure on land, India has more
than 600 Protected Areas, covering approximately 5%
of the total geographical area of the country, in a
network of National Parks, Wildlife Sanctuaries, and
Conservation Reserves. India has special programmes
for some high-profile endangered species like tigers
and elephants. In 2010, the country level status
assessment for tigers showed an increase in their
number to an estimated 1706 from an estimated 1411
in the year 2006. Subsequent to becoming a party to the
CBD, India has taken the following steps towards
maintenance of biodiversity.
 India has passed and notified the Biological
Diversity Act, 2002. The act primarily addresses
access to genetic resources and associated
knowledge by foreign individuals, institutions or
companies, to ensure equitable sharing of benefits
arising out of the use of these resources and
knowledge to the country and the people.
 As per the provision of the Biological Diversity Act
2002, a National Biodiversity Authority has been
set up at Chennai on 1st October, 2003 to facilitate
implementation of the Act. In compliance with the
provisions of the Act, states have formed State
Biodiversity Boards and at local level, Biodiversity
Management Committees have been formed.
 India chaired the Group of Like Minded Mega
diverse Countries (LMMCs) for a period of two
years (March, 2004 to March, 2006). India played

an important role in the development of a common
position of LMMCs for the negotiations for
developing an international regime on access and
benefit sharing.

formats easily accessible by patent examiners. This
Library promotes the objectives of the Nagoya
